LOAD-SECURING MEANS FOR INDUSTRIAL TRUCKS.

Application filed. August 19, 1921. Serial No. 493,702.

To all whom it may concern Be it known that I, CLYDE E. CoonRAN, a citizen of the United States. residing at .Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Load-Securing Means for Industrial Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawmgs.

This invention relates to industrial trucks wherein the truck is prpvided with mechanism for raising, transporting, and depositing articles such as rolls of paper.

The general object of the invention is to provide means in a truck such as the type described which will prevent the load from beingdisplaced while it is being loaded, unloaded or transported.

A specific object of the invention is to provide means co-operating with holding means carried" on" one end of the truck to maintain a load in position on the holding means.

A further object of the invention is to-provide load securing means on the load holding meansv which is adapted to enter the core cavity of a paper roll for the purpose of holding said roll on a conveying truck. Ad- 50 ditional objects of the invention will be apparent. from the following description taken in connection with the accompanying drawmgs.

In my application for Letterslatent on an industrial truck, filed July 9, 1920, Serial No. 394933,I have illustrated and described a load handling means which is particularly adapted to the loading and unloading of large paper rolls. Figs. 1 and 2 in the prescut application are illustrations in a conventional way of such a truck. Fig. 1 shows my device associated with an industrial truck designed especially for the purpose of handling paper rolls, the roll or handling means being illustrated in a vertical position; Fig. 2 shows the position of the load and load supporting means in transportable position; Fig. 3 is a side elevation of a load securing means supported by the load handling means, while Fig. 4: is a top plan view of the same. Fig. 5 is a front elevation of the load securing means.

The truck may be comprised substantially of a frame 10 and boom 11 pivotally secured to the end thereof and boom actuating means 12 consisting of a Winding mechanism and a flexible member 13. The end of the flexible member or cable is secured to a load supportlug apron 14: a suiiicient distance from a pivot mounting 15 on the boom to efiect a turning movement of the apron. When the winding mechanism drawson the cable the boom apron and load will be tilted to an inclined position as illustrated in Fig. 2. While the boom is in the tilted position'the apron and load. may be swung to a horizontalv position about the pivot 15 upon a slackening of the cable by the winding mechanism. Suitable telescopic members 16 serve to limit the inward and outwardswing of the boom.

The load supporting apron 14, as described in the application hereinbefore mentioned, may be comprised of a semi-circular metallic sheet rigidly secured to the pivot member 17, which is associated with the pivot bearing 15. A bottom projecting portion 18 may be arranged to lie in a horizontal position on the ground or floor, as the case may be, when the load carrying apron is in a substantially vertical position. This projecting member may have an outer tapered edge 19 'to facilitate the forcing thereof under the load by a backward movement of the truck.

Any convenient means may be used-to secure a load positioned on the member 18 to the apron It as for example, a strap extending around the roll. and the apron. It is quite desirable, however, that means be provided in. combination with such a truck whereby a load may be secured on the load carrying apron while ina vertical position as shown in Fig. 1 and which will not'necessitate the operator leaving his posit-ion on the truck. 7

To this end, I have rovided a novel device having an adjustab mounted on the upper portion of the apron which may be swung into and out of engagement with the load as illustrated by the full line and dot-and dash-line positions in Fig. 2. This arm may have a downwardly extending portion 23 terminating in a ballpoint 2% which is adapted to be lowered into the core cavity of the paper roll prior to the raising of the roll in which position it may rest as the boom and apron are tilted inwardly over the truck. The roll will thus be retained in position on the apron by the le arm 22 pivotally member 22 and the bottom portion 18. This member may be raised and lowered from the operators position by any convenient means such as a cord 25 secured to the movable elements of the device and a sheave 26, the latter being supported a considerable distance above the apron by an upwardly extending supportingmember 27,- whereby the cord may clear the top of the boom. It is essential that the load securing means be adaptable for holding any length or diameter'of roll on'the truck. To obtain this result, I have provided an adjustable pivot support'in association with the upper portion of the apron and an extensible conuee tion between the support and arm and telescopically connected to a tubular member 29. Suitable lock-screws 31 serve to main tain these members in rigid relation after the desired extensible adjustment of the arm is obtained.

In order to obtain a transverse or angular adjustment of the arm 22, I provide a bifurcated bearing member 34 hax in'g a pivotal relation to the support 21 and upon which the inner end of the member 29 may be movably secured by any s'uitablemeans such as a lock-bolt 35, a nut 36. The tubular member may terminate in a solid portion 37 having an opening formed therein through which the bolt may pass. The load securing mechanism may be longitudinally adjustable with relation to the apron 11 for the handling of different lengths of rolls. Hence the apron may have a longitudinal slot 39' extending downwardly from the upper endthereof in which the deviw may be slidably mounted. Suitable slideways 40 and 41 are arranged to cooperate with the slot edges of the apron and ma be of sufiicient width to obtain con siderab e bearing contact between the surfaces of the apron 14 and the pivot support 21. Any convenient means may serve to retain the device, in position on the apron as for example, set screws 44, which may be carried by the pivot support and when tightened are adapted to clamp the slot edgesof the apron to the inner surface of the slide ways formed in the pivot support. A suit able pivot 'pin 45 carried by the pivot support may serve as a pivot bearing for the bearing members 34.

From the foregoing description ofmy device, it is readily understood that the invention may be embodied in a variety of devices, however, the embodiment herein illustrated, while being simple in character,

without leaving his position on the truck. 1

Likewise, as the load is being shifted from the inclined to a horizontal position the delifting member pivoted to swing thereon and in one position to approximate the vertical, said'load lifting member comprising a body engaging portion and an end engaging portion, and a second load engaging member co-operating with the first to hold a load on said truck, the last named member being connected to the first named member by a universaljoint.
